You've got a generation of young men - almost all are young men - in situations of great economic hardship, where they don't really have work. The chances of them making a decent life for themselves, of making a family, living in a kind of decent, happy way, are very, very remote. It's very hard for them to ever even have that as a dream, so when people are that deprived of the ordinary hope of human beings, it creates anger. And that anger can be channeled by unscrupulous persons, whether secular or religious leaders, and there's been a lot of that.
